What or Why DNF?

DNF or Dandified YUM is the next generation version of yum. 

DNF is a software package manager that installs, updates, and removes packages on RPM-based Linux distributions. It automatically computes dependencies and determines the actions required to install packages. DNF also makes it easier to maintain groups of machines, eliminating the need to manually update each one using rpm. Introduced in Fedora 18, it has been the default package manager since Fedora 22. So, in this post I’m not going to discuss the usage of DNF rather on why and advantages of using it. By default, DNF comes pre-installed on RHEL8.x releases. The "yum" command is a symbolic link to the "dnf" binary now.
